Since ancient times, trees have had a fascinating role in the spiritual world. Biblical scriptures mention trees as in the “tree of life” and the “tree of knowledge of good and evil.” Buddha was known to have reached enlightenment as he sat and meditated. Druids were known to practice worship among sacred groves of trees. In Islam, trees are to be treated with respect and not be unnecessarily harmed. Planting trees is regarded as an act of charity and the planter receives blessings from all those who benefit from it. Lights make us feel cozy, mellow, and warm, and so the combination of lights and trees make us calmer and happier.
